近几年来,井陉县进行产业结构调整,新栽植大枣14.5万亩,野生酸枣嫁接大枣200万株。但由于立地条件差,年降雨量少,管理粗放,枣的座果率高低不稳,病虫果较多,严重影响着红枣的产量和品质。该县经过反复试验,认真分析,总结出了一套适合本地的瘠薄山地大枣提质增效技术。一、土肥水科学管理 1.深翻树盘。由于山地枣园没有灌溉条件,只能靠自然降水来满足枣树生长结果的需要。因此,要在雨季前(6月中、下旬)和雨季过后(8月中、下旬)进行两次深翻树盘,深度20～30cm,雨后及时除草。
In recent years, Jingxing County industrial restructuring, planting 145,000 acres of new jujube, jujube wild jujube grafted 2 million. However, due to poor site conditions, less annual rainfall, extensive management, jujube fruit rate is high and low instability, pests and diseases more serious impact on the yield and quality of the jujube. The county after repeated tests, careful analysis, summed up a set of suitable for the local barren mountain jujube quality improvement and efficiency of technology. First, soil and water scientific management 1. Deep down tree plate. As the mountain jujube no irrigation conditions, can only rely on natural precipitation to meet the needs of jujube growth results. Therefore, it is necessary to carry out deep sowing of tree trays twice before the rainy season (middle and late June) and after the rainy season (mid-to-late August) at a depth of 20-30cm and to weeding in time after the rain.
